Patented Sept; 11, 1906.

Application filed June 10,1 05. Serial d. 264.551.

To all whom it may concern.-

Be it known that I, HENRY NOEL POTTER,

a citizen of the United States, and a resident of New Rochelle, county of Westchester, State of New York,have invented certain new and useful Improvementswin Methods of Making Paint, of which the following is a s ecification,

I havediscovered'an improve method of.

making paint containing silicon monoxid, whereby the peculiar: properties of the latter are'certai'n to exert their maximum influence;

I find that if. silicon -monoxid ,powderl be" mixed dry with another-pigment and the two ground together: and then added to oil or other vehicle the effect ofiithe silicon monoxid,

(Si O) is lost or Inasked.- The fine particles of silicon monoxid .(SiO) appear to stick to the relatively larger, particles of the other pigment, and thus lose their identity as separate 28 particles. The same to a lesser'degreeis true if dry SiO be added toa paint containing another pigment or if a dry pigment be added to a silicon-monoxid (SiO) aint. The best eflect is secured by mixing iO to the extent properly prepared.

of ten per cent; to twenty per cent. salv, with oil or vehicle'and' adding this to-a paint of other pigment-and vehicle pro erly prepared bg rinding;:& before the si icon-mOnoxid iO) ,paintis added. After adding the latter the .tw'o' "may {be paddled together or ground/though the latter 'i's'no advantage over the former if thepaint to which the silicon-monoxid (SiO) paint isadded has been l'cl'aim asm invention+ "The metho vof preparing mixed paints containing silicon monoxid which consists in HENRY NOEL POTTER.
